Shark attack! No, this wasn’t actually underwater. Well it was, but not really. This is from the shark exhibit at the Pittsburgh Zoo. There’s a glass tube at the bottom of the shark tank where visitors can walk through and view the sharks from below. On TV it looks like sharks swim along rather slowly, but in real life they’re actually quite fast. I had a bit of a hard time getting an in-focus shot with an entire shark in the frame, but after many tries, I did!
